Why is Zirconium in Period 5?
Let me ask you a question.
How many shells does Zirconium have?
It’s 4. Right?
You have already seen the bohr model of zirconium atom in the above table.
From the Bohr model, it can be found that the number of orbits or shells in zirconium is 5. Hence, as zirconium has 5 orbits, it lies in period 5 of the Periodic table.
Why is Zirconium in d-block?
Before knowing this reason, first of all I want to ask you a simple question.
How can you determine the blocks-wise position of elements?
The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.
For example; the electron configuration of zirconium is [Kr] 5s2 4d2.
So the last electron of zirconium enters the d-subshell or d-orbital.
Hence, zirconium is the d-block element.
Is Zirconium a Transition Metal? Why?
Yes, Zirconium is a transition metal because it has incompletely filled d-orbital in its ground state.
Let me explain the exact meaning of this.
According to the definition of transition metals;
The element should compulsorily have incomplete d-orbitals, either in their ground state (M) or most common oxidation states (M1+, M2+, etc) then only they are called transition metals.
Now, the ground state of Zirconium means its normal state in which it has neither gained nor lost any electron/s.
So the ground state of Zirconium is Zr.
And the ground state electronic configuration of Zirconium is [Kr] 5s2 4d2.
In this state, if we see the electron configuration of Zirconium, then it possesses incomplete d-orbitals.
Because, there are only two electrons in the d-orbitals.
In order to have the complete d-orbitals, there must be 10 electrons in it.
But in the ground state electronic configuration of zirconium, you can see that it has only 2 electrons in d-orbitals.
Thus, Zirconium has incomplete d-orbitals.
And hence, as Zirconium has incomplete d-orbitals, it is considered as a transition metal.
8 Interesting facts about Zirconium
Interesting facts about zirconium element are mentioned below.
- The name zirconium was derived from the Persian word “Zargun” (meaning gold color).
- The abundance of zirconium in earth’s crust is around 165 ppm (parts per million) by weight.
- In ancient ages, zirconium was used in decorative items as well as in jewelry.
- Martin Heinrich Klaproth was a German chemist who discovered zirconium in 1789 from Berlin (the sample of zirconium silicate was from Sri Lanka).
- In the entire world, the total amount of zirconium production is around 7000 tons per year.
- Australia and South Africa are the places from where most of the zirconium is obtained.
- Around 58% of the world’s total zirconium production is done in Australia.
- Zirconium is also present in the Sun as well as meteorites.
